BOTTLE-CLOSING ATTACHMENT.

Application filed January 17, 1912.

To all whom; it may concern:

Be'it known that I, ANGELO C. RovnLLI, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Closing Attachments, of which the following is a specification.

My invention relates to improvements in bottle closing attachments, the object of the invention being to provide an improved attachment for any ordinary bottle neck, which is designed to permit the liquid to be poured out of the bottle, but prevent its return so that the bottle cannot be refilled.

A further object is to provide improvements of this character which are constructed of glass or porcelain, rendering them on tirely sanitary, and so construct the parts that a ball, by its weight or gravity, holds the valve in closed position even though the bottle be in a horizontal position, requiring the bottle to be tilted to an angle greater than that of 90 to open the valve.

A further object is to provide improve ments of this character which are of extremely simple inexpensive construction, and which may be permanently secured to a bottle neck, preventing possibility of removal without detection.

\Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1, is a view in vertical section illustrating my improvements in normal closed position. Fig. 2, is a similar view showing the bottle neck in a horizontal position. Fig. 3, is a similar view showing the bottle neck inverted, and Fig. 4, illustrates in top plan, side elevation, and bottom plan the dome 6.

1, represents an ordinary bottle neck such as in common use on bottles, and I would have it understood that my improved attachment is adapted for use on the ordinary style of bottle, not requiring any special construction of bottle or neck.

A ring 2 is positioned on the end of the bottle neck, and is provided with a downwardly projecting circular flange 3 which snugly fits within the bottle neck, and a ring or gasket 4 preferably of cork, is inserted between the ring and the end of the Specification of Letters Patent.

bottle neck. This gasket 4 is of the entire width of the bottle neck at its flanged outer end, while the ring extends over approximately but one half of the thickness of the bottle neck for a purpose which will hereinafter appear.

The ring 2, at its outer edge, is made with an integral circular upwardly projecting flange 5, which confines the lower end of a dome 6. This dome 6, illustrated in detail in Fig. 4, is made with an internal shoulder 7 between which, and the ring 2, a valve 8 is movable, and the opening movement of the valve is limited by the said shoulder 7. This valve 8 is shown cup shape, but may of course be of other shapes, and is normally held in closed position by means of a ball 9 located within the dome.

The ring 2 constitutes a seat for the valve, and the dome is of general conical shape, so that it insures the tension of the valve in closed position, even when the bottle is tilted to a horizontal as Will more fully hereinafter appear.

The dome, throughout its lower end, is made with a circular series of recesses 10 constituting passages for the liquid, and on the outside of the dome, segmental flanges 11 are provided. These flanges are staggered with relation to each other, and constitute a bafliing device to prevent the entrance of a tool to tamper with the valve.

A casing 12 incloses the dome 6, bears snugly against the flanges 11, and at its lower end closely confines the outer edge of ring 2, and bears upon the gasket 4, the lower end of said dome being made with an annular grooved enlargement 13, and when this enlargement is secured against the gasket, the parts will all be securely held in position.

The outer end of the casing is open for the egress of liquid, and may be closed by any ordinary plug or stopper 14;.

In Figs. 1, 2, and 3, I illustrate a simple means for securing the casing 12 to the bot.-

tle neck, and this means consists of a metal ring 15 which is positioned around the lower end of the casing, and the upper end of the bottle neck, and is bent so as to confine the enlargement 13 of the casing 12 and the annular flange 16 on the end of the bottle neck, and furthermore is depressed as shown at 17 to project into the groove of the enlargement 13. When this band is once fixed, it cannot be removed without detection, and

hence acts as a lock to hold the parts in position on a bottle neck. I call attention particularly to the internal shape of the dome 6, which is of general conical form with the side walls more straight than curved. In other words, the internal walls constitute inclined planes, and this is most clearly seen in Fig. 2 where the bottle is shown in a horizontal position.

It will here be noted that even though the bottle is in ahorizontal position, the ball moving down the inclined surface of the dome, still holds the valve in closed position, thereby preventing the bottle from being refilled even in this position. It is therefore required that the bottle be tilted to an angle greater than 90 before the valve will open, and will not completely open until turned completely upside down as seen in Fig. 3. When open, the liquid flows through the recess 10 around the outside of the dome 6, and out through casing 12.

The ring 2, valve 8, ball 9, dome 6, and casing 12 are all composed preferably of glass, porcelain, or other earthenware which will not corrode, and which will be perfectly sanitary.

It will be noted that my improvements occupy but relatively small space, and may be secured to the neck of any ordinary bottle, adding but little to the space required for the bottle in shipping and storing, and may be attached to a bottle at a very low cost.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A bottle closing attachment, comprising a ring adapted to be positioned on a bottle neck and having a circular flange on its outer face, a valve normally positioned against said ring inside of the flange, a dome confining the valve and positioned against the ring inside of the flange, said 4 dome of internal conical form and having openings therein, a ball in said dome nor mally pressing the valve against the ring, enlargements on the dome spaced apart, and a casing adapted to be secured to a bottle neck outside of the ring and pressing against the enlargements holding the dome in position on the ring, substantially as described.

2. A bottle closing attachment, comprising a ring adapted to be positioned on the end of a bottle neck and constitute a valve seat, a valve normally against said seat, a ball normally against said valve, a dome confining ball and valve, said dome having internal shoulders limiting the movement of the valve, said dome of internal truncated conical form, enlargements on the outer face of said dome, a casing bearing against said enlargements and holding the dome on the ring, said enlargements spaced apart, whereby a passage is permitted between the dome and the casing, said dome having openings therein, and means for securing said casing to the bottle neck, substantially as described.

3. An attachment of the character described, comprising a ring, a flange on said ring adapted to project into a bottle neck, a circular flange on the outer edge of said ring, a valve engaging the ring, a dome located on the ring and confined within the last-mentioned flange of the ring, said dome having an internal annular shoulder limiting the opening movement of the valve, said dome having passages formed therethrough in its lower portion, and said dome of general truncated conical form, a ball in said dome normally in engagement with the valve, a casing around said dome and ring, integral staggered enlargements on the outer face of said dome engaging the inner face of the casing and constituting baflies, an annular enlargement on the lower end of said casing, and a fastening device securing said enlargement on the end of the bottle neck, substantially as described.

In testimony whereof I have signed my 'name to this specification in the presence of two subscribing witnesses.
